	* Released and tagged Tcllib 1.4 ========================
	* 

2003-05-05  Andreas Kupries  <andreask@activestate.com>

	* prioqueue.tcl: Applied patch by author Michael Schlenker
	  <mic42@users.sourceforge.net>. Refactors internals for
	  speed. Passes the prioqueue testsuite.

2003-04-25  Andreas Kupries  <andreask@activestate.com>

	* queue.man: Documentation fix. peek/get throw errors if more was
	  requested than in the queue. The documentation talked about
	  returning empty strings. Thanks to Michael Schlenker
	  <mic42@users.sourceforge.net> for the report.

	* prioqueue.test: Extended to check for stable insertion.
	* prioqueue.tcl (__elementcompare): Bugfix, makes insertion stable.
	* prioqueue.man: New, documentation.

	* skiplist.man: Typo fix. Thanks to Michael Schlenker
	  <mic42@users.sourceforge.net> for the report.

2003-04-24  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* tree.bench: New file, beginnings of a benchmark suite for the
	  data structure 'struct::tree'.

2003-04-23  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* tree.man: Changed name to struct_tree.man. Was in conflict with
	  tree manpage of BLT.

2003-04-22  Andreas Kupries  <andreask@activestate.com>

	* graph.man: Switched cgraph reference to a purl supplied by the
	  cgraph author, and added wiki reference.

2003-04-16  Andreas Kupries  <andreask@activestate.com>

	* prioqueue.tcl (__elementcompare): Failures in testsuite fixed,
	  patch provided by original author, Michael Schlenker
	  <mic42@users.sourceforge.net>.

2003-04-15  Andreas Kupries  <andreask@activestate.com>

	* skiplist.man:
	* skiplist.tcl:
	* skiplist.test: New files. Patch #553980 submitted by Eric Melski
	  <ericm@users.sourceforge.net> on behalf of Keith Vetter.

	* prioqueue.tcl:
	* prioqueue.test: New files. Patch #607085 submitted by Michael
	  Schlenker <mic42@users.sourceforge.net>.

2003-04-15  Andreas Kupries  <andreask@activestate.com>

	* tcllib_list.man: Changed name to struct_list.man. Allows for
	  usage of struct outside of tcllib, not as big a coupling.

	* graph.tcl: Redone the setting up of namespace a bit to prevent
	  problem with the generation of a master package
	  index. strcut.tcl bailed out with an error because the namespace
	  was net set up when using [pkg_mkIndex] in this directory.

2003-04-13  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* graph.test:
	* graph.man:
	* graph.tcl: Added code to look for the C-implementation, cgraph,
	  first, and to fall back to the Tcl implementation if cgraph is
	  not present (#720348). The documentation links to the place
	  where cgraph can be had from. Note presence of cgraph when
	  executing the testsuite.

2003-04-12  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* list.man: Changed name to tcllib_list.man to prevent a clash
	  with tcl's manpages.

2003-04-11  Andreas Kupries  <andreask@activestate.com>

	* struct.tcl:
	* list.man:
	* matrix.man:
	* pool.man:
	* queue.man:
	* record.man:
	* stack.man:
	* tree.man:
	* pkgIndex.tcl:  Set version of the package to 1.3.

2003-04-09  Andreas Kupries  <andreask@activestate.com>

	* list.man:
	* list.test:
	* list.tcl: Added 'lcsInvertMerge'.

2003-04-08  Andreas Kupries  <andreask@activestate.com>

	* list.man:
	* list.test:
	* list.tcl: Added and documented commands [iota], [equal], and
	  [repeat]. Extended the testsuite.

2003-04-02  Andreas Kupries  <andreask@activestate.com>

	* list.cl:
	* list.test: Fixed SF tcllib bug #714209.

	* ../../../examples/struct: Added example applications for usage
	  of longestCommonSubsequence and lcsInvert.

	* list.tcl:  Added commands 'reverse', 'assign', 'flatten',
	* list.man:  'map', and 'fold' to the suite of list functions.
	* list.test: 

2003-04-01  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* list.man:  New files, extended list manipulation
	* list.tcl:  facilities. Started out with Kevin Kenny's
	* list.test: implementation of the algorithm to find the longest
	             common subsequence of two sequences, aka lists.
		     Added myself a method to invert a LCS into a
		     description of differences instead.

2003-04-01  Andreas Kupries  <andreask@activestate.com>

	* record.test: Applied changes provided by Brett Schwarz
	  <schwarzkopf@users.sourceforge.net>. His comments: I had changed
	  the return when encountering a circular record; previously I
	  returned "", but now I return an error. This fixes record.test
	  to reflect the change. Part of fix for Tcllib SF Bug #709375.

	  Additional changes by myself: Reformatted (proper tcl
	  indentations). Renumbered so that all tests have unique id
	  numbers (Before all tests had id 0.1).

2003-02-25  David N. Welton  <davidw@dedasys.com>

	* matrix.tcl: Require Tcl 8.2 because of string map.  Use string
	map instead of regexp.

2003-01-16  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* graph.man: More semantic markup, less visual one.
	* matrix.man:
	* pool.man:

	  test suite too.

	* tree.tcl (_move): Accepted patch by Brian Theado
	  <btheado@users.sourceforge.net> fixing the behaviour of mov, SF

2002-05-27  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* matrix.man: Fixed typo (graph -> matrix).

	* struct.tcl: Added pool files to list of files to source.

	* pool.man: New documentation for pool based upon the original
	  HTML manpage.

	* pool.html:
	* pooltest.tcl:

	  <e.leunissen@hccnet.nl>. Modified code to be a sub-namespace of
	  ::struct, made it a part of the struct package. No regular
	  testsuite yet (see pooltest.tcl for the irregular testsuite).

2002-05-08  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* graph.n: This file is out of sync.
	* graph.man:
	* graph.test:
	* graph.tcl: See tree, for arcs and nodes.

	* tree.man:
	* tree.n:
	* tree.test:
	* tree.tcl: Accepted FR #552972 (new methods append, lappend,
	  getall, keys, keyexists) for tree structures.

2002-04-01  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* matrix.tcl: Fixed SF Tcllib #532791 about unsetting of elements
	  in linked arrays as reported by Ken Jones
	  <kenj@users.sourceforge.net>. Unsetting an element in a linked
	  array now sets the corresponding cell in the matrix to the empty
	  string, and the corresponding elements in other linked arrays
	  are now unset too.

	* tree.man: New file, doctools manpage.

2002-03-25  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* matrix.tcl: Fixed bug #532783 reported by Ken Jones
	  <kenj@users.sourceforge.net>. Any operation adding new material
	  to a linked matrix causes a circular trace (op -> "MatTraceOut"
	  -> "MatTraceIn" -> set cell) and the inbound trace fails because
	  the data structures are not uptodate causing the range checks in
	  "set cell" to fail. Fixed by breaking the cycle. Calls to
	  "MatTraceIn" are now disabled while we are in "MatTraceOut".

2002-03-15  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* matrix.man: Added example of formatting a matrix using tabular
	  reports (See tcllib module "reports" too.). Fixes #530207.

	* graph.n:
	* graph.tcl: Applied patch #483125 provided by Frank Pilhofer
	  <fp@fpx.de>. The patch adds key/value information for the whole
	  graph and extends the selection methods 'arcs' and 'nodes' to
	  allow selection based on keys and their values.
